RANGE.

SPECIFICATION forming part of Letters Patent No. 247,777, dated October 4, 1881.

Application filed February 7, 1881. (Model) I To all whom 'it may concern Be it known that I, DAVID H. NATION, of St. Louis, Missouri, have made a new and useful Improvement in Ranges, of which the following is a full, clear, and exact description, reference being bad to the annexed drawings, making part of this specification, in which Figure 1 is a view in perspective, showing that portion of a rangewith which the improveto ment in question is immediately connected, a

portion of the outer and inner plates being broken away to exhibit the interior construction and the damper being turned as for direct draft to the exit; and Fig.2, a similar view, but

1 showing thedamper turned to direct the heatcnrrents around the oven.

The same letters denote the same parts.

The present invention is an improvement in ranges having three flues, and it is a modification of the construction patented to me June 1,1880, and numbered 228,270. In the construction referred to a division-strip extends from the back side of the range to the opposite side thereof at a pointjust beyond the diving- 2 fines. The presentimprovement has especial relation to this portion of the range.

A represents the improved range, having the fire-place B, the flue 0, leading from the fire-place, the diving-fines D D, the side bot- 0 tom flues, E E, the center bottom flue, F, the

ascending flue G, the flue-space H, the flue N,

leading from the space H along the back side ofthe range to the escape N, and the oven I, all substantially as in the original construction. In place, however, of the flue-strip extending in rear of the diving-fines from the side a of the range continuously to the opposite side, a, of the range, the flue O and space H are made to be separated by the strips K K,

which are arranged beyond the diving-fines D D, and a central damper, Mthat is, for direct draft the damper is turned down, as in Fig. 1, and the heat-currents are then from the flue 0 into the flue-space H; thence into the flue N, and out atN, as indicated by the arrows. 5

To heat the oven the damper is turned up, as in Fig. 2, and the course of the heat-currents is then from the flue 0, down the diving-fines D I), and through the flues E E, F, and G into the space H, and thence through the flue N to the exit N, as indicated by the arrows in the last-named figure. The strips K K may be extensions of the plates 70 7c. The damper may be arranged either at the near or farther side of the strips K K.

I am aware of and disclaim the construction shown in Letters Patent No. 285,350, granted Giles F. Filley December 14, 1880.

I claim- 1. In a range, A, the combination of the flues O, H, and N, said flues O and H being partly separated by the strips K K, arranged and extended from the sides a and a, respectively, and leaving an opening at the top between the inner ends of the strips at the center of the range, as described and shown. k

2. In a range, A, the combination of the flues G, D D, E E, F, G, H, and N, and the central damper, M, and strips K K, said strips extending, respectively, from the sides a and a, and forming an opening at the center of said range to be closed by said damper, substantially as described.

DAVID H. NATION.
